Tag: Tentacled Sea Cucumbers (Dendrochirotida and Apodida Sp.)

There are a number of "suspension feeding" species of Sea Cucumber (Holothuroidea in local waters, although how varied they are is unknown.

They vary in appearance from small, burrowing species of which only the tentacles are visible, to larger, more typically shaped species such as the Thorny Sea Cucumber (Colochirus Quadrangularis).

Although it is usually possible to place an individual within its correct family, accurately determining the species, or even the exact genera is often very difficult.

For this reason, i've decided to place all species belonging to the orders Dendrochirotida and Apodida together as a group. In some cases, an exact species may be identified if there is a strong possibility of a match.

Magnum Sea Cucumber (Neothyonidium Magnum)

If i am correct in my assumption that this is a Magnum Sea Cucumber (Neothyonidium Magnum), then this photograph would indicate that they are present in differing colour variations.

This Magnum Sea Cucumber (Neothyonidium Magnum) was photographed at one of their most common locations, below Chaloklum Pier!

Warty Sea Cucumber (Cercodemas Anceps), Black Sea Cucumber (Holothuria Atra), Medusa Worms (Synaptula Lamperti)

This Warty Sea Cucumber (Cercodemas Anceps) was photographed under Chaloklum Pier, Koh Phangan (one of the best places to find one) and was obviously feeding at the time as its colourful "retractable feeding tentacles" are fully extended.

Godeffroy's Sea Cucumber (Euapta Godeffroyi)

The Godeffroy's Sea Cucumber (Euapta Godeffroyi) is one of a number of related species of Sea Cucumber that are often found clinging to Barrel Sponges (Xestospongia Testudinaria).
These large sponges are often covered in a layer of algae, which is one of the main food sources of the Godeffroy's Sea Cucumber.
